What is the difference between these two L2vpn technologies?
The bits of info I was able to find but still don't answer my question-
VPWS:
Virtual private wire service (VPWS)—Has a characteristic of a fixed
relationship between an attachment-virtual circuit and an emulated
virtual circuit. VPWS-based services are point-to-point (for example,
Frame-Relay/ATM/Ethernet services over IP/MPLS).

X-connect:
Xconnects are used to connect 2 distant sites that can use any of
these technologies : Frame-Relay, PPP, Ethernet, ATM, that's why
xconnects are also called Any Transport over MPLS (AToM).
Best Answer
VPWS and Xconnect is about the same technology. VPWS is the name of technology, xconnect - keyword for configuring pseudowire. You can find different naming like VLL, L2VC, PWE3, etc. Essentially they are referring to the same technology of p2p l2 connections.
You can find more info in RFC 4664
For instance section 1.3 says:
